ICCT life-cycle analysis finds no climate benefit in using LNG as marine fuel

Green Car Congress

The results of a new analysis by the International Council on Clean Transportation (ICCT) show that, when combined with a trend toward higher methane leakage and combustion slip, there is no climate benefit from using liquefied natural gas (LNG) as a marine fuel—regardless of the engine technology. First, it contains very little sulfur.

Audi introduces new CNG A3 Sportback

Green Car Congress

Operation with natural gas or biomethane makes the compact model economical and more climate-friendly with low emissions. Its turbocharger with variable turbine geometry makes optimal use of the exhaust gas energy for early and harmonious torque development. With this fuel, driving is nearly climate-neutral.

Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small airborne particles of pollution. Small particles in exhaust from burning fossil fuels creates “seeds” on which water vapor in the air can condense into cloud droplets. This makes the clouds brighter, or more reflective.

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

For offsets to be credible, a ton of CO 2 -equivalent emissions from an offset project should equate to a ton reduced from a covered emission source, such as a smokestack or exhaust pipe. To be credible, as noted above, an offset should equate to an emission reduction from a direct emission source, such as a smokestack or exhaust pipe.

Tomorrow's Hydropower Begins With Retrofitting Today's Dams

Cars That Think

With wind and solar prices dropping, it can be easy to forget that two-thirds of the globe’s renewable energy comes from hydropower. They help stop floods and supply farms and families with water, but they’re not generating electricity—especially in developing countries. Yes, say climate scientists, but with a caveat.

2022 Lexus LC 500 Convertible Review – Still Got It

The Truth About Cars

Usually, convertible versions of sports coupes suffer from chassis flex and wind/road noise and the like, but this car doesn’t, at least for the most part – you might get some chassis flex when hitting a severe enough bump, but it’s rare. But otherwise, the LC 500 convertible feels as fresh as ever.

Volkswagen and LichtBlick Partner on Home Combined Heat and Power Systems; LichtBlick Plans a SchwarmStrom for 2,000 MW of Decentralized Power

Green Car Congress

The EcoBlue units consist of a natural gas engine that powers a generator; the exhaust gas is used for the heating component. While the ZuhauseKraftwerk will only generate power on demand, the heat produced at the same time will be stored, allowing reliable supplies of heating energy and warm water to the building at all times.
